• Measure outer diameter (d) at position as shown.

• If reduction appears in position other than (d), regard it as (d).

• If measured value exceeds limit (large difference in dimensions)

replace connecting rod bolt with new one.

Limit: 7.75 mm (0.3051 in)

INFOID:0000000011279983

DESCRIPTION

 *For the service parts, the grade for fitting cannot be selected between a piston pin and a connecting rod.

(Only 0 grade is available.) The information at the shipment from the plant is described as a reference. 

• The identification grade stamped on each part is the grade for the dimension measured in new condition.

This grade cannot apply to reused parts. 

• For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the

measurement with the values of each selection table.

• For details of the measurement method of each part, the reuse standards, and the selection method of the

selective fitting parts, follow the applicable procedures.

HOW TO SELECT A PISTON

When New Cylinder Block is Used:

• Check the cylinder bore grade on rear left side of cylinder block,

and select a piston of the same grade.

• If there is a corrected stamp mark on the cylinder block, use it as a

correct reference.

When a Cylinder Block is Reused:

1. Measure the cylinder block bore inner diameter.
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner

diameter of the "Piston Selection Table". Select the piston of the same grade.

Piston Selection Table

• For the piston selection table, refer to 

EM-125, "Cylinder Block"

.

NOTE:

• The piston is available together with piston pin as an assembly. 

• The piston pin (piston pin bore) grade is provided only for the parts installed at the plant. For service parts,

no grades can be selected. Only 0 grade is available.

HOW TO SELECT A CONNECTING ROD BEARING

When New Connecting Rod and Crankshaft are Used:

1. Apply big end inside diameter grade stamped on connecting rod

side face to the row in the "Connecting Rod Bearing Selection

Table".

2. Apply pin diameter grade (B) stamped on crankshaft front side

to the column in the "Connecting Rod Bearing Selection Table".

• Journal diameter grade (A)

3. Read the symbol at the cross point of selected row and column

in the "Connecting Rod Bearing Selection Table".

4. Apply the symbol obtained to connecting rod bearing grade table

to select.

When Crankshaft and Connecting Rod are Reused:

1. Measure dimensions of the big end inner diameter of connecting rod and outer diameter of crankshaft pin

individually.

2. Apply the dimension measured to the "Connecting Rod Bearing Selection Table" below.

(A) : Oil splash
(B) : Small end diameter grade
(C) : Reference code
(D) : Bearing stopper groove
(E) : Reference code
(F) : Cylinder No.
(G) : Big end diameter grade

Undersize Bearing Usage Guide

• When the specified oil clearance is not obtained with standard size connecting rod bearing, use undersize

(US) bearing.

• When using undersize bearing, measure the bearing inner diameter with bearing installed, and grind the

crankshaft pin so that the oil clearance satisfies the standard. 

 Bearing Undersize Table

Unit: mm (in)

CAUTION:

In grinding the crankshaft pin to use undersize bearings, do not

damage the fillet R (All crankshaft pins).

HOW TO SELECT A MAIN BEARING
